Coffee: The Most Popular Beverage on Earth

Coffee lovers around the world who reach for their favorite morning brew probably aren’t thinking about its health benefits or risks. And yet this beverage has been subject to a long history of debate. But yet, this coffee is most popular beverage on earth.

Coffee is a drink prepared from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It is the most popular hot drink in the world.

Seeds of the Coffea plant's fruits are separated to produce unroasted green coffee beans. The beans are roasted and then ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often used to mask the bitter taste or enhance the flavor.

Coffee and Health

Coffee is an intricate mixture of more than a thousand chemicals. [1] The cup of coffee you order from a coffee shop is likely different from the coffee you brew at home. What defines a cup is the type of coffee bean used, how it is roasted, the amount of grind, and how it is brewed. Human response to coffee or caffeine can also vary substantially across individuals. Low to moderate doses of caffeine (50–300 mg) may cause increased alertness, energy, and ability to concentrate, while higher doses may have negative effects such as anxiety, restlessness, insomnia, and increased heart rate. [2] Still, the cumulative research on coffee points in the direction of a health benefit. [3,4] Does the benefit stem from the caffeine or plant compounds in the coffee bean? Is there a certain amount of coffee needed a day to produce a health benefit?

Vitamin B2 (riboflavin)

Magnesium

Plant chemicals: polyphenols including chlorogenic acid and quinic acid, and diterpenes including cafestol and kahweol

One 8-ounce cup of brewed coffee contains about 95 mg of caffeine. A moderate amount of coffee is generally defined as 3-5 cups a day, or on average 400 mg of caffeine, according to the Dietary Guidelines for Americans.

So this it

It is a myth that darker roasts contain a higher level of caffeine than lighter roasts. Lighter roasts actually have a slightly higher concentration!

Coffee grinds should not be brewed more than once. Brewed grinds taste bitter and may no longer produce a pleasant coffee flavor.

While water is always the best choice for quenching your thirst, coffee can count towards your daily fluid goals. Although caffeine has a mild diuretic effect, it is offset by the total amount of fluid from the coffee.
